We are scripting deloy scripts using .js files and want to have them automatically run at deploy time. But we need a proper return code:

al01 /home/kgorman$ cat test.js | mongo
MongoDB shell version: 1.5.2-pre-
url: test
connecting to: test
type "help" for help
> use content
switched to db content
> fdkjfkdjfkdb.bookStyles.ensureIndex(

)

al01 /home/kgorman$ echo $?
